December 2000 Page 2B-1 CHAPTER 2B. REGULATORY SIGNS Section 2B.01 Application of Regulatory Signs Standard: Regulatory signs shall be used to inform road users of selected traffic laws or regulations and indicate the applicability of the legal requirements. Regulatory signs shall be installed at or near where the regulations apply. The signs shall clearly indicate the requirements imposed by the regulations and shall be designed and installed to provide adequate visibility and legibility in order to obtain compliance. Regulatory signs shall be retroreflective or illuminated to show the same shape and similar color by both day and night, unless specifically stated otherwise in the text discussion of a particular sign or group of signs (see Section 2A.08). The requirements for sign illumination shall not be considered to be satisfied by street, highway, or strobe lighting. Section 2B.02 Design of Regulatory Signs Support: Most regulatory signs are rectangular, with the longer dimension vertical. The shapes and colors of regulatory signs are listed in Tables 2A-3 and 2A-4, respectively. Exceptions are specifically noted in the following Sections. The use of educational plaques to supplement symbol signs is described in Section 2A.13. Section 2B.03 Size of Regulatory Signs Support: The "Standard Highway Signs" book contains sign sizes and letter heights for regulatory signs used on conventional roads, expressways, freeways, and low-volume roads, and under special conditions. Standard: The sizes for regulatory signs shall be as shown in Table 2B-1. Sect. 2B.01 to 2B.03 Page 2B-2 December 2000 Table 2B-1.
